Abstract: 119,418. Poilvache, C., and Strauven, M. J. J. May 6, 1918. Stapling and discontinuous wire-stitching. - A stapling or wire-stitching machine is provided with a head in which various sized cutting and shaping and driving tools can be readily substituted. The head comprises front and rear plates A, B, Fig. 2, secured together by screws C, the rear plate being provided with a groove E in which slide a driver bar G and a cutting and shaping tool F. The tool F, Fig. 4, has screwed to its lower end an extension F<1>, which slides in a groove D, Fig. 2, in the front plate A, and two staple-forming projections F<3>, Fig. 4, which are slightly countersunk in the tool to prevent lateral play; one of the projections F<3> is formed with a knife edge F<5>. The driver bar G, Fig. 2, has a driver G' secured to its lower end bv screws G<2> so as to be flush with the bar, the driver being of just sufficient width to slide between the projection F<3>. The driver bar carries pins G<3>, G<6> which slide in slots E<1>, F<6> in the plate B and the tool F respectively, and near its upper end has secured to it a spring-pressed detent H normally in contact with the upper end of the tool F but adapted to be displaced by the engagement of an extension H<2> with a cam surface J on the plate A. This plate has screwed to it a spring L to which an anvil M is secured by screws M<1>; a groove M<2> is formed in the front face of the anvil to receive the wire N. In operation, the tool F is moved downwards with the driver bar G to cut the wire and bend it about the anvil, after which a cam surface on the extension F' engages a rounded portion M<3> of the anvil and presses the latter outwards, leaving the staple held between the projections F<3>. The detent H is then tripped by engagement with the plate A, and the driver bar G moves relatively to the tool F to drive tho staple into the work. Plates K, O, secured by screws to the plate B, take the wear of the projections F<3> and the driver G<1>. By releasing the screws C, the plate A, B may be, separated to enable the projections F<3>, driver G, and anvil M, to be changed for driving staples of a different size.

Abstract: 699,120. Extruding. COMPTOIR INDUSTRIEL D'ETIRAGE ET PROFILAGE DE METAUX. April 2, 1951 [May 3, 1950], No. 7639/51. Class 83 (iv). A method for hot extruding metals consists in inserting between the ingot and the die a non-homogeneous lubricating material made up of welded layers of vitreous material having a thermal diffusivity which varies from one layer to another and which partly or completely melts but remains viscous when submitted to the heat of the ingot. The non-homogeneous material may be in the form of a cylinder made of a number of glass layers welded together. The layers may be of multi-cellular or fritted glass of varying densities the layer of highest density being also the layer of highest diffusivity. Layers of multi-cellular glass may also be interposed between layers of fritted or solid glass. The lubricating material is placed between the die and the ingot with the layer of high diffusivity nearest to the ingot. The material may be made by placing two layers of glass grains each layer of different grain size in a mould the upper layer of smaller grain being interspersed with fine grains of a carbonaceous material which will develop gas upon heating. The mould is heated to a temperature sufficient to fuse the layers together and form an upper layer of multi-cellular glass and a lower layer of fritted glass.

Abstract: 145,837. Entwistle, W. S. March 27, 1919. Electric oscillations, producing.-The pressure of the gas or vapour in the arc chamber is kept above atmospheric pressure by connecting the chamber by a pipe to a gasometer floating in a liquid seal, thus preventing air from entering the chamber and forming an explosive mixture. The arc chamber A is connected by a pipe B to the interior of a gasometer C floating in a tank D and partially counterbalanced by adjustable weights E. To permit the gas to be continuously renewed, an outlet pipe F furnished with a valve G projects through the top of the gasometer C. The lower end of this pipe F lies near the level of the liquid in the tank D so that when the arc is extinguished and the gasometer falls as the gas contracts, the pipe F is sealed by the liquid. The pipe may be slit so that the sealing takes place gradually. The liquid to be vaporized in the chamber A is fed thereto by a drip feed having a sufficient head of liquid to overcome the pressure in the chamber. The head may be maintained by a float operating a needle valve which regulates the flow of liquid into the drip chamber.

Abstract: 5 88 ,2 9 5 . Luminescent materials. SYLVANIA ELECTRIC PRODUCTS, Inc. April 29, 1944, No. 8086. Convention date, Dec. 8, 1942. Drawings to Specification. [Class 39 (i)] A mixture of luminescent to give white light is prepared by selecting phosphors with trichromatic coefficients, each of winch is located on the same straight line substantially tangential to the locus of the trichromatic coefficients of black body radiation between temperatures of 2575‹ C. and 6227‹ C. An example is a mixture of manganese activated zinc beryllium silicate with silver activated zinc sulphide. The coefficients of the silicate can be adjusted by varying the ratio of zinc to beryllium and by varying the firing time and activator concentration. The sulphide coefficients can be varied by choice of activators, their concentration and firing time and temperature. As the area of a powder exposed to the bombardment of an electron beam is affected by the particle size, if coarse powder is used for a particular component, a greater amount should be used than if fine powder were employed.
